Introduction
A three-jaw chuck self-centering card disc is an important part of the power drive in modern machinery. It is widely used in automobile engines, aerospace transmissions, ship propulsion, valves, motors and many other industrial applications. It is the best choice to replace manual card disc when it comes to high precision, large diameter and complex parts. The three-jaw chuck self-centering card disc has an adjustable radial clearance and flexible installation, which is suitable for different size parts. This article will introduce the technical parameters of the three-jaw chuck self-centering cards disc.
Technical Parameters
The three-jaw chuck self-centering card disc is mainly composed of a chuck body, eccentric shaft, radial clearance adjusting mechanism and locking mechanism. The length dimension of the chuck body is controlled between Φ150~Φ1000, and the length tolerance is 7μm. The allowable radial misalignment is 5μm after the lock nut is tightened. The rotating eccentric shaft is generally made of stainless steel. The radial clearance adjusting mechanism is composed of a adjusting nut, a decreasing plunger, a ball bearing and its lock nut, etc. It can adjust the max radial clearance to 0.21~2.2 mm. Other technical parameters include repeat positioning precision, radial clearance range, axial displacement and so on.
Applications
The three-jaw chuck self-centering card disc is applicable for large diameter and complex parts with high precision. It is suitable for machining automobile engines, aerospace transmissions, ship propulsion, motors and valves. It has the characteristics of high precision, good concentricity and repeatable positioning. Moreover, it is used in applications where multiple operations need to be performed, such as drilling and reaming.
Conclusion
The three-jaw chuck self-centering card disc is an important part of the power drive used in modern machinery. It has an adjustable radial clearance and flexible installation which is suitable for different size parts. The chuck body length dimension is controlled between Φ150~Φ1000 and the allowable radial misalignment is 5μm after the locknut is tightened. The rotating eccentric shaft is made of stainless steel and the radial clearance adjusting mechanism is composed of a reducing plunger, a ball bearing and its lock nut. The three-jaw chuck self-centering card disc is applicable for machining large diameter and complex parts with high precision.
